PROBLEM SOLVING TASKS
Tape drive does not become ready
1. Determine if the tape drive is online by pressing the Scroll
button until the message display shows the Status display.
2. If the tape drive is offline, follow the procedures listed in the
“Place the tape drive online” section of chapter 7, “Offline
printing tasks.”
3. If the drive still does not become ready, the cartridge may be
inserted incorrectly. Remove the cartridge from the transport
and insert it again.
4. If there is an error code message in the message display,
record the error code, press the Unload switch, and try the
operation again.

5. If the drive still does not become ready, call for service. If
there is an error code message on the message display,
record the code and report it to the service representative.
